Quote, originally posted by briang » The way H&R lists springs is "length-rate"
The 180-070 in the front is the length of the spring in milimeters, 180 and the rate 070. The 300-050 for the rear is the spring lenght in milimeters, 300, and the rate 050.
The rates are listed in newtons/mm of travel and can be converted to lbs/inch as follows, 1 newton / millimeter = 5.71014715 pounds force / inch.
So 70N/mm = 399.7 lbf/in
and 50N/mm = 285.5 lbf/in

and are they progressive or linear

Sorry to bring this back from the dead, and I didn't go through every page, but I thought that Eibach prokit springs were progressive, whereas on the first page it indicates that they're linear.

Rides somewhat bouncy to me, just installed yesterday and its a daily driver. Handles very well, but I don't have much to compare it too.

Hey man u seem to know your stuff really well. I was hoping you could help me w/a question. I have a 2000 GTI (1.8T) that i bought used, already dropped (not sure how much of a drop) on 225/40/18's. I need to get either shocks or both shocks & springs (i think the springs are still good) & i want stiffer than facory (not much room b/w tire & wheel well). What name & shock rate should i look for?
vuu, what do you use for shocks? I am creating a SOLO car and was wondering about spring rate. Most coilovers use a 35-336 F and a 285-280 R spring rate. I thought this would be good with sufficient bar force and less compliant busings.
The problem is with more force there is more wear...do you have addditional welds for the suspension supports...control arm, strut mount, rear bushing mounts...etc?
Is trhere any way this could at least be subdivided by chassis? It's frustrating trying to wade through it in this format. I've got an A1 on H&R sports/Koni yellows and want something that will actually hold the back end up. Problem is I'm TRYING to find out the rate of what I HAVE. FRUSTRATING!!!!
I cannot believe that there is no exhaustive listing of spring rates for our cars.
